Ortolan Bunting
SEXING:
According to Svensson (2023) sexing of 1cy is not recommended due to individual variation. Most ad can be sexed using the below described criteria. However, more difficult birds are some times seen and should be left unsexed.
1cy September (Mongolia). Due to individual variation, 1cy is not recommended to sex. [90764531]
1cy September (Mongolia). Some young birds are more rufous-buff below and future studies may show whether this is relevant for sexing. [90764478]
2cy+ male September (Mongolia). Greyish-olive breast-band (sometimes dark mottled) separate yellowish throat and rufous-buff belly. Crown finely dark streaked. [90764551]
2cy+ female September (Mongolia). Breast distinctly dark-streaked and lacking greyish-olive breast-band. Crown with distinct dark streaking. [82406635]
